If you need explanation I can explain
Let’s do 3x - 8 ≤ 23 first.
You need to rearrange this so that x is on its own.
+8 to both sides
3x ≤ 31
/3 on both sides
x ≤ 31/3
Then the second, -4x + 26 ≥ 6
-26 from both sides
-4x ≥ -20
/-4 on both sides
x ≥ 5
So x is greater than or equal to 5, which can also be written as 5 ≤ x
And for the first one, x is less than or equal to 31/3, which can still be written as x ≤ 31/3, so your final answer is:
5 ≤ x ≤ 31/3
3/15x, 2/10x and 0.20x are equivalent to 1/5x
Step-by-step explanation:
- Step 1: Verify whether the expressions are equal to 1/5x
⇒ 3/15x = 1/5x (Common factor is 3)
⇒ 2/10x = 1/5x (Common factor is 2)
⇒ 0.50x = 1/2x Not equivalent to 1/5x
⇒ 0.20x = 1/5x (Decimal equivalent)
= 9 * 10^5 * 3 * 10^10
= 27 * 10^5 * 10^10
= 27 * 10^15
= 2.7 * 10^16 - The best selection appears to be the first option.
Good luck :)
